Abstract

Abstract

Low Earth Orbit navigation system has a large number of satellites and Doppler frequency deviation, so the search space of the receiver with cold start is huge and the acquisition speed is slow. A Code-phase Shift Key and Linear Frequency Modulation (CSK-LFM) navigation signal waveform is proposed, the LFM modulation improves the Doppler tolerance of the signal, and the multiple access broadcast of different satellites is realized by different pseudo-code phases, which can greatly compress the three-dimensional search space of satellite number, time delay, and Doppler. Simulation and experimental results show that when the signal strength is 40dBHz, the acquisition performance of CSK-LFM signal is about 1dB higher than that of traditional Direct Sequence Spread Spectrum (DSSS) modulation navigation signals under the same conditions, and the signal search space can be reduced to 1/10 of that of DSSS modulation.
